【摘要】 研究了超高压条件下,乙醇水溶液对肉桂皮中肉桂醛的萃取方法,探讨了压力、保压时间、溶剂浓度和固液比等因素对萃取工艺及抑菌活性的影响。结果表明:超高压萃取肉桂醛的最佳工艺参数为:压力200MPa,保压时间5min,固液比1∶10,提取溶剂为80%乙醇,各因素影响大小顺序为:压力>固液比>溶剂浓度>时间;超高压萃取物中肉桂醛含量及抑菌活性分别是常压的1·4和1·3倍。更多还原

【Abstract】 The extraction of Cinnamaldehyde from Cinnamomum cassia bark by high hydrostatic pressure extraction(HHPE) with liq-ethanol was studied,the influence of extraction pressure,time of holding pressure,solvent concentration and solute/solvent ratios on the extraction procedure and antimicrobial activity were investigated.The results showed that the optimum procedure parameter of HHPE Cinnamaldehyde were:extraction pressure was 200MPa,time was 5min,solute/solvent ratio was 1:10,extracting solvent was 80% ethanol.The sequence of influence of each factor from highest to lowest was shown as follows:pressure>solute/solvent ratio>concentration of solvent>time.The content and antimicrobial activity which was used HHPE was 1.4 and 1.3 times of extracted by normal pressure.更多还原
